2 Claims, 2 Drawing Figures APPARATUS FOR WASHING LUMPY NON-METALLIC MATERIALS The present invention relates to apparatus for washing lumpy nonmetallic materials, mostly crushed or broken stone and gravel or grit used as a concrete aggregate, as well a for washing up metallurgical flux materials, metallic ores, and the like.

Known in the art are devices for washing gravel and broken stone, comprising a horizontal row of parallel-arranged perforated spouts or drums, wherein the material is washed with water. The spouts are imparted vibratory movement from a vibration exciter or jigger located therebetween so that the longitudinal axes of both the spouts and the jigger are parallel to each other.

Washing is efiected separately in each of the spouts in the course of movement of the material therein due to vibration.

However, the hitherto known washer devices, due to a low filling percentage or level (0.5 or 0.6) of the spouts or drums thereof, provided an insufficient time for the material to wash, for which reason said washer devices are not employed for washing large-sized fractions of the material admixed with ball clay.

Moreover, the now-employed washer devices require much water to be consumed for the washing procedure (0.8 to 1.5 m. per 1 ton of the material to be washed) and they do not provide for control of the washing time in dependence with the degree of contamination of the material to be washed.

It is an object of the present invention to eliminate the disadvantages mentioned above.

It is the main object of the present invention to provide a device for washing lumpy nonmetallic materials which is capable of a quality washing procedure; has a higher filling percentage or of the spouts, and a longer period of time for the material to stay in the spouts so as to provide quality washing of large-sized fractions with admixtures of ball clay; will consume less washing water and allow the control of washing time depending upon the degree of contamination of the material to be washed.

This object is accomplished in that in a device for washing lumpy nonmetallic materials, mostly broken stone, gravel and flux materials, according to the invention perforated spouts are arranged tierwise one above the other in such a manner that in each pair of adjacent spouts they are inclined or are sloped oppositely with respect to each other so as to convey the material being washed from the upper spout to the lower spout.

The character of this invention will be better understood upon a consideration of a specific embodiment of a device for washing gravel and broken stone with reference to the accompanying drawings, wherein:

F lG. l is a longitudinal section view of a device according to the present invention; and

FIG. 2 is a sectional taken on the line lI-ll in FIG. 1.

Now referring to FIGS. 1 and 2, the device comprises a pair of perforated spouts, viz a top spout l and a bottom spout 2 mounted at an angle to each other, a transfer chute 3 connecting said spouts with each other, a vibration exciter or jigger 4 with unbalance-mass weights 5, adjustable-height control gates or weirs 6, an irrigation or sprinkler system 7, a tray or tub receptacle 8 to accumulate waste water and a springcushioned suspension 9.

The axis 10-10 of a shaft or spindle ll of the vibration exciter 4 is perpendicular with respect to the longitudinal axes 12-12 and 13-13 of the respective spouts l and 2.

The device operates as follows.

Gravel or broken stone is charged into the top spout l of the device in the direction indicated by the arrow A. By the vibration produced by the vibration exciter or jigger 4 the charged material is conveyed along the spout 1 while being washed with water fed by the irrigation system 7. Then the material washed in the top spout 1 passes via the transfer chute 3 into the bottom spout 2, along which the material is vibration-conveypd and dischar ed in the direction of the arrow B.

he height of e weirs 6 deten-nmes both the filling percentage or level of the spouts 1 and 2 and the washing time.

Water from the top spout is accumulated in a collector sump or pan l4 wherefrom it flows down through chute 3 into spout 2 to wash the material while in the bottom spout 2 whence, in turn, water flows into the tub receptacle 8 and further is discharged through a pipe 15 in the direction of the arrow C.

The herein-disclosed device is capable of washing gravel or broken stone with a spout filling percentage or level equal to 0.9 or 1.], whereby the washing time is extended by 60 to percent as compared to the similar devices of conventional construction, the throughput capacity of the device remaining unaffected. Thus high-quality washing of large-sized fractions with admixtures of ball clay, is achievable.

On account of the fact that water from the top spout l is fed to the bottom spout 2, the total water consumption for washing is reduced from 0.8-1 .5 mP/ton to 0.40.7 mP/ton.

The device in contemplation'can likewise be implemented to comprise two pairs of spouts arranged one above the other which is conductive to a higher washing efficiency of the device.

What is claimed is:

l. A device for washing lumplike generally nonmetallic materials consisting essentially of broken stone, gravel and flux material or the like, said device comprising; a pair of perforated spouts positioned in tandem one above the other, said spouts being inclined one relative to the other, means for introducing material to be washed into the upper spout at the upper end thereof, means to wash the material on said upper spout as the material descends therealong, means at the lower end of the upper spout to convey all the material washed in the upper spout to the lower spout, means to collect wash liquid passing through the perforated upper spout and convey the wash liquid to the lower spout; means resilient mounting said spouts; and vibration imparting means interposed between said spouts and fastened thereto to impart vertically reciprocating motion to said spouts so as to facilitate movement of said material being washed therethrough.

2. A device as claimed in claim 1 wherein said vibration imparting means comprises at least one rotatable unbalanced weight adapted to impart reciprocating motion of predetermined amplitude and frequency to said spouts and means in each spout to control the liquid level therein.
